I cannot find any reference in docs. > dead_vnops.c exports a variable dead_vops which is used in vclean() as the operation vector for a vnode that can no longer be used, such as after revoke(2) or when the filesystem has been forcibly unmounted. Providing a dummy vector like that avoids adding checks to each VOP_* call. fifo_vnops.c provides the functions used in the struct vops vectors for FIFOs on all filesystem, providing the actual behavior of FIFOs everywhere.
